Description
Technical field
The present invention relates to air supporting field.
Background technique
Along with the development of science and technology, normal adopt gas lubrication to replace common mechanical lubrication, form air film in the object gap of pressurized gas being introduced relative movement, avoid directly contact to realize frictionless motion.
The mode that air-floating apparatus forms air film is different, air supply method is also different, usually be all utilize tracheae to introduce gas in hyperbaric chamber, but no matter adopt which kind of plenum system, tracheae all must not produce disturbing influence to air-floating apparatus, for the air-floating apparatus that some move relative to source of the gas, there is a very large difficult problem in air supporting air feed.If side is by the folding hinge plate of the vertical placement of hinge links, bottom realizes planar frictionless by multiple floating cushion and launches motion, require not introduce any external force when launching, if each floating cushion introduces tracheae from outside, floating cushion moves with hinge, and steam line can produce the impact of disturbance on the motion stopping floating cushion, and air feed circuit is many, easily twist, bend, be wound around, be not easy to installation and maintenance; Usually by attached for air supply pipe onboard from one piece be incorporated into another block simultaneously air feed to the floating cushion this plate, but hinge plate from fit-state to expansion time can be subject to the disturbing influences such as joint tracheae is bending, winding, the expansion of interference hinge.
Summary of the invention
Bend the deficiency of the impact of disturbance in order to the tracheae solving existing air-floating apparatus, the invention provides a kind of can the rotating for air flotation device without friction of unaffected by disturbance of air pipes of air feed continuously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of rotation air feeder realizing serial air supply, comprise air-bearing shafts, a pair air supporting cover and gas storage jacket, described air suspension shaft sleeve is contained in air supporting cover, described air supporting cover has two, described air supporting cover is peripheral to be fixed with gas storage jacket, hyperbaric chamber is formed between described gas storage jacket and two air supporting covers, air-bearing shafts, described gas storage jacket there is suction port and is communicated with hyperbaric chamber, there is axial hole at described air-bearing shafts center, end bracket enclosed is passed through at described air-bearing shafts two ends, there is air outlet at the upper and lower two ends of described air-bearing shafts, and described air-bearing shafts is positioned at the uniform multiple radial direction through hole of hyperbaric chamber part; Described air supporting cover along the circumferential direction uniform throttle orifice, described throttle orifice has two groups at least, described gas cover is beaten blind hole vertically and is formed inlet hole from hyperbaric chamber one side end face, described inlet hole communicates with throttle orifice, described air supporting cover two ends and gas storage jacket are tightly connected, described air supporting cover is surveyed circumferentially to go up near hyperbaric chamber one and is uniformly unloaded pore, described unloading has angle between pore and inlet hole and mutually isolated, described bleeder port is opened a circle on the circumferential surface and to be lost heart groove, described gas storage jacket is got through hole and communicates with disappointing groove.
Further, the air outlet at the upper and lower two ends of described air-bearing shafts is communicated with by tracheae.
Further again, there is sealed groove at described air supporting cover two ends, mounting O-shaped rings sealing in described sealed groove.
Mentality of designing of the present invention is: according to air-bearing principle, realize air-bearing and air supporting overlap between rotate without rubbing, again by adopting the mode of self pressurized gas air feed, pressurized gas being introduced from air supporting cover and draws from air-bearing shafts, thus realizing rotating air feed without friction.
Pressurized gas enter hyperbaric chamber from gas storage jacket suction port, a pressurized gas part in hyperbaric chamber enters axial hole from the radial direction through hole air-bearing shafts and flows out air feed to next air-floating apparatus from the air outlet at air-bearing shafts two ends, another part enters in air supporting cover from suction port air supporting cover, in the gap that air-bearing shafts and air supporting overlap, air film is formed by throttle orifice, sub-fraction is also had directly to enter in the gap of air supporting cover and air-bearing shafts, air supporting has put unloads pore, the pressurized gas entering gap are discharged from unloading pore after damping seal, one end that air-bearing shafts overlaps gap with air supporting communicates with air, the other end unloads pore, because this gap internal memory is in pressure gradient, the pressurized gas part entered in gap by throttle orifice is flowed out from side, gap, another part is discharged by unloading pore.
Folding hinge plate is expanded to by fit-state in the process of 180 ° under the effect of hinge, be arranged on axis of rotation when two pages of folding hinge plates launch without friction rotation air feeder, base, air supporting cover are fixed with one block of plate, air-bearing shafts is connected with another block plate, therefore pressurized gas are just delivered to another block plate from one block of plate, not by the disturbance of tracheae rotating bending, outer diameter without friction rotation air feed is less than or equal to the thickness of hinge plate, avoids multiple the rotation between air feeder without friction of fit-state mutually to disturb.
Because the gap precision between air supporting cover and air-bearing shafts requires very high, therefore in installation process, leave certain surplus, then make air-bearing shafts press close to air supporting cover by the pressurized gas in hyperbaric chamber.
Beneficial effect of the present invention is: can air feed continuously, unaffected by disturbance of air pipes.
